Teeth whitening is a common cosmetic dental topic, but the right starting point is not a shade chart. Your natural tooth colour, oral health, existing dental restorations and sensitivity can all influence the discussion.

What whitening can and cannot change

Whitening approaches are generally intended to change the appearance of natural tooth surfaces. Existing crowns, veneers and fillings may not respond in the same way, so they should be considered when planning a cosmetic result.

Why sensitivity matters

If you experience sensitivity or have concerns about your gums, tell your dentist before trying a whitening product or treatment. An assessment can help identify whether the approach is appropriate.

Questions to ask before you begin

• What may be contributing to the current shade of my teeth?
• Are my teeth and gums suitable for whitening now?
• How could existing restorations affect the appearance afterward?
• What results and limitations should I realistically expect?

A personalised discussion is more useful than a promise

A dentist can help you compare options and consider your individual circumstances. Avoid relying on a guaranteed shade or outcome; ask for advice grounded in your own oral health.
